Dr Nick Taylor: Call me old fashioned, but what use is a macro lens without an aperture ring?

Seems that people forget that in the "old good days" we used to use something called "bellows" for macro photography....now we can only reach 1:1 ratio in the "new fashion" macrophotography.....seems that we have lost something in the way.....Nikon has lost the capability they had in the field of macro photography, who knows why.....
